System Documentation

What problem does it solve?

Diagnose and design JSON serialization and deserialization behavior for Kotlin plus Jackson in Spring applications. Use when DTOs fail to deserialize, default parameters or nullability behave unexpectedly, date-time or enum formats drift, polymorphic payloads are involved, PATCH semantics must distinguish null from absent, or ObjectMapper changes risk breaking existing API or message contracts.

Core Features & Use Cases

  • Diagnose module presence and alignment with jackson-module-kotlin, JavaTimeModule, and other relevant modules
  • Verify constructor semantics, default parameters, and nullable vs non-null fields
  • Validate wire-format handling across MVC, WebFlux, Kafka, and persistence boundaries, including polymorphic types and enum/date-time formatting

Quick Start

Provide the failing JSON payload, the relevant Kotlin DTOs, and any ObjectMapper customizations so I can diagnose and fix the serialization behavior.
